To provide an aspect of a novel display device using a light emitting
element which is composed of a cathode, an EL layer and an anode, and a
manufacturing device of the display device. According to the present
invention, dual-sided emission display can be performed in one sheet
white color light emitting panel 1001 in which, for example, different
images can be displayed on a topside screen and backside screen (full
color display, monochrome display or area color display). Two polarizing
plates 1002, 1003 are formed by shifting the position thereof with an
angular deviation of 90 degrees each other so as to prevent outside light
from passing through the pane, thereby realizing a black display when not
displayed.
